Can I import my spell templates as a player to a game for all players to use?

I am not the DM of a game but can I implement my purchased spell templates into the games I play or does the DM have to purchase them? And if so how do I go about doing that?

You mean spell template images? If the Owner/creator of the game (presumably your GM) promotes you to GM temporarily, you can place your graphics on the table top. Depending on how you plan to use them during the game, it will require some setup after that. He cannot draw them from his art library, but he could set each one as a default token for a blank character sheet and keep those in a folder in the journals tab. How do you normally access them during a game?

My former GM had it so we can just pull them out and use them (like a 20' radius for a fireball).  We just find the 20' radius token and drag it to the map.  I believe he purchased the owlbear emporium area affect tokens. I have some already purchased just trying to figure out how the we as players could get them into the game to use so the GM won't have to purchase them

Assigning them as tokens to characters is the best way, then. Make the characters controllable and in the journals of "All Players". Size them as you want them before assigning as default for each character. That way they will pull out at the proper scale, which would not be true if they were just graphics. Also, during the set-up, be sure to right click on each one and select "is drawing". This will prevent them from showing bars and circles when selected. Most important: Save as default as the last step . Otherwise, when you pull them out and place them on the board, you will not see whatever were the last modifications you made. Saving as default is the equivalent to saving a document.

I hadn't thought of this technique. I have saved area effect art as decks, a different deck for each area effect size. Within the 4" diameter deck, for example, I store fire, earth, air, and water blast graphics. FWIW, I create the graphics at about 70% translucency. I'm not sure of the pros and cons versus the method Keith suggests.
