I'll take it that there is no seperation at all in them, ok i'm no expert but i'll try help. First of all water the soil so that it is moist and very carefully cut around the soil for each little plant as far a gap as you can get very careful not damage the roots. Get the soil ready in the new pots , take the little plants out holding them by the root ball and gently place in new pots, water them again and let them settle into there new pots.
