Names for relatives

[Vukabular]

In the Serbian language next to the names for the ancestors I listed in the topic "Names for ancestors" we have different names for all relatives listed below. Does this only exist in the Serbian language and the people?

otac i majka - father and mother

očuh i maćeha - the spouse of a non-blood parent with the child

sin i ćerka - son and daughter

pastorak i pastorka - children of spouses with whom they are not related

brat i sestra - male and female child of the same parents

polubrat i polusestra - male and female child having one parent in common

stric i strina - father's brother and his wife

ujak i ujna - mother's brother and his wife

tetka i teča - father's and/or motbrother's sister and her husband

bratanac i bratanica - brother's childrens

sestrić i sestričina - sister's childrens

svekar i svekrva - husband's parents

tast i tašta - wife's parents

snaja - son's wife

zet - daughter's husband

šurak i šurnjaja - wife's brother and his wife

svastika i pašenog - wife's sister and her husband

zaova i svojak - husband's sister and her husband

jetrva - wife of husband' s brother...

I probably skipped some because I can't remember them all.

I doubt that. Russian used to have a pretty developed system, but it wasn't quite uniform from the start, and was getting progressively simplified during the last couple of centuries or so.
Note that certain languages may have systems which are more refined in certain aspects. For example, Semitic languages tend to consistently oppose father's and mother's relatives (so no tetkas), while most Altaic ones oppose elder and younger brothers and sisters (and sometimes spread that to uncles and so on).

I have found some similarities with Sanskrit

Father-in-Law	श्वशुरः	Śvaśuraḥ
Mother-in-Law	श्वश्रूः	Śvaśrūḥ

Husband’s Brother (Younger)

देवरः

Devaraḥ

In Serbian husband's brother is dever

 

[Vukabular]

From Wiktionry
PIE *swéḱuros m (non-ablauting) "father-in-law"
Serbian svekar i svekrva - husband's parents

 

[Awwal12]

In Serbian husband's brother is dever

No wonder, it's déver' in Russian. Proto-Slavic had a considerable amount of kinship terms inherited from PIE, so did Sanskrit. Cf. also Baltic "dieveris".
Curiously, German "Schwager" with the same meaning is cognate to Slavic *svekry; apparently there was some confusion between husband's relatives among Germanic tribes.

 

[Olaszinhok]

Are those terms used in everyday conversation or can you only find them in an ethnographic museum?

 

[Vukabular]

We use these terms on a daily basis.

The Russian analogues (add some terms and take some of the others) were used on a daily basis until recently. But Russian society mostly consisted of traditional peasant communities up to the early XX century, no wonder about that.

 

[Yendred]

What do you mean by "the spouse of a non-blood parent with the child"?

Apart from this, in French, some terms are identical as they are not distinct depending on the exact relationship and sex of the related and the relative, as in your language:
père et mère - father and mother
fils et fille - son and daughter
beau-fils et belle-fille - children of spouses with whom they are not related
frère et soeur - male and female child of the same parents
demi-frère et demi-soeur - male and female child having one parent in common
oncle et tante - father's brother and his wife
oncle et tante (same as previous) - mother's brother and his wife
neveu et nièce - brother's childrens
neveu et nièce (same as previous) - sister's childrens
beau-père et belle-mère - husband's parents
beau-père et belle-mère (same as previous) - wife's parents
bru or belle-fille - son's wife
gendre or beau-fils - daughter's husband
beau-frère et belle-soeur - wife's brother and his wife
belle-soeur et beau-frère - wife's sister and her husband
belle-soeur et beau-frère - husband's sister and her husband
belle-soeur - wife of husband' s brother...

Same, similar or different terms for almost all those relatives @Vukabular mentioned for the Serbian language are used in everyday conversation in Macedonian and Bulgarian languages too.
