Hi McCoy.. Welcome to BTALK..
Nice lil beginner bonsai you have there. The two which are questionable are not doing so good.. the one on the right is most probably dead and the left is hard to say from the pic but it loks dead also ..
the other two are holding in there waiting to be outside in a shady spot during midday.. and full to partial sun morning and afternoon. Outdoors they will get real full sun not filtered through glass as they are getting indoors. Most Bonsai are grown outdoors. The soil is ok ..? Is is like what is visible throughout the entire pot? ..watering with this type of soil can be a bit tricky. A fine spray should saturate the entire soil surface till water runs out the bottom of the pot. Daily watering might be a bit much, since these trees are a little over potted.. but under normal conditions they will be fine. Stick your finger in the soil to check for moisture content .. if moist they are ok.
Your trees may have been recently potted and before they were out of shock they were moved and moved and ...
Get them outside and give them a few weeks.. hopefully they will be fine.
