Well, the one on the left looks a lot like my blackcurrant bush and the two on the right look a lot like my gooseberry bushes. They will be better identified when leaves appear, of course and even better when fruit appear.
Presumably this is a new plot? My advice would be to let them grow on for this year and see what results. You might get a pleasant surprise. If you really want to plant your own, leave these in situ until your newly planted ones start fruiting well. Otherwise you'll have a period of no fruit.
