Apart from humans, are there other species which routinely stand on two legs as well?

Kangaroos.

They skip, but when still they stand on their fours don't they?

Well they have those two little legs that they use when they want to stand anywhere they want and then there are the ostrichs for example that they use their two leg for walking or running

Ostriches and other sea birds yes. But land birds seldom do.

Basilisk lizards

[Beowulf]

(idk their name in English) Also these guys can spend quite a lot of time standing with their two legs

Yes, you are right, but apparently they had some prehistoric cousins in Australia that could and did walk on two legs. They went extinct 30.000 years ago. They are called sthenurines and the biggest members of this extinct kangaroo family may not have hopped at all.

According to new research, the extinct "sthenurine" family of giant kangaroos, up to three times larger than living roos, was able to walk on two feet.

Today's kangaroos can only hop or use all fours, but their extinct cousins' bones suggest a two-legged gait.
