If you can grow peaches you should be ok with nectarines and apricots.
I take it you are growing outdoors?
Helping pollination with a brush helps enormously at blossom time, and of course, protection from frost and rain is an essential early in the season.
Apricots can be difficult if they are growing too strongly.
They, like so many fruit trees, seem to crop heavier if they are not allowed to romp away at the early stage of the year.
Any fruit tree that is growing too strongly will put growth before fruit.
