Does anyone know how many starfish I can keep in 180g tank ? I have a brittle and serpent right now. My daughter loves watching them and was thinking about getting 2 more .

as long as they have plenty to eat and are compatible (including territorial size), you can get as many as you want.

There is really no fixed limit, IMO, to the number of brittle/serpentstars you can keep. In a 180, unless you are a brittlestar freak like myself, you are likely to only put maybe 4 or 5 and be happy...when even more could fit. In the wild, they occur in high densities under "choice" rocks...perhaps a dozen or more of different species. I've kept 4 in an 8g and 5 in a 15. Just keep them fed.
The restrictions come in with other stars. For a blue Linckia, for example, I would say just one. Other Linckia, perhaps two. Those depend entirely on the amount of LR since they can not be spot fed. Predatory seastars like chocolate chips? Quite a few as they can be fed (but are not appropriate for a reef).
But brittlestars/serpentstars can be kept in relatively high numbers...just be warned that they may pose a threat to some small fish and shrimp. Not everyone has these issues, but it may be instinctive for some individuals.
