You have not filled in your flair but I'll assume Canada, so you've got a long way until a proper spring.
Your conifers will take a bit more time to ID. They need to be outdoors, but if you put them outside right now, they'll die from climate shock. When you put them outdoors in the Spring, they will be in for a weird year, having not had any wintertime dormancy (think back to what it's like when you miss an entire night of sleep), so you should prepare yourself for the possibility that you'll lose them. If they manage to survive till fall 2020, keep them outdoors forever after that. These are mountain plants and need to experience winter cold to survive more than a couple growing seasons.
If you are on the western half of Canada, visit nurseries in your area and see if you can find bags of pumice. If you're in the eastern half of Canada, you can consider something like Turface or similar. Both of these should be extremely affordable compared to bonsai soil. In addition to these, get sphagnum moss. You want the stuff that hasn't been pulverized into dust.
Get a large mixing tub and sieve and sift out all of the dust and small particles in whichever inorganic media you selected (i.e. the pumice vs. turface vs. other fine gravel-like substance). Aim for a consistent particle size so that your final mix will have lots of spaces in for oxygen.
Take the sphagnum moss and soak it for a good 20 minutes , pushing it down occasionally to ensure it gets fully wet. Then mix the moss and pumice/turface/etc into a blend. Plant your conifers into this without disturbing their existing roots and keeping a bit of the existing.soil Note that many if not all pines require beneficial mycorrhizal fungi in their soil to ensure that the roots are able to take up nutrients, so you may want to look into inoculating your soil somehow.
If this sounds complicated and you just want to order something that works and have the cash to burn, order something online like Boon's bonsai soil.
Your conifers will require full sun and to be outdoors. The pine, assuming it's a pine, will want to dry out a little bit between waterings. The spruce, assuming it's a spruce, will want to be a smidgen more moist than the pine. Start looking into bonsai care calendars and learning the overall annual cycle of activities and maintenance tasks (this will include feeding, pruning, thinning/needle plucking, shoot plucking, etc).
EDIT: One more thing -- avoid bonsai pots for your conifers for now. What you want for maximum success and best root growth is a pond basket. The ones you want look like this: https://www.amazon.com/Laguna-Sturdy-Plastic-Square-Planting/dp/B000256E5I/ref=sr_1_9?keywords=pond+basket&qid=1573233867&sr=8-9 These are great because they will absolutely guarantee that you cannot overwater your conifers, and you can use the basket as a support for wiring.
What I'll be doing is, I'm going to order [these](https://www.amazon.com/Laguna-Sturdy-Plastic-Square-Planting/dp/B000256E5I/ref=sr_1_4?ie=UTF8&qid=1541539284&sr=8-4&keywords=pond+baskets) and slip them into these pots so they can have the room to grow and recover. The reason for this is you want the tree to have access to air and the roots will grow radially and "air prune." These pots will ultimately promote better root growth which in turn will promote better health of the tree.
