Well done so far, great change to weight and run sounds good.
For a sprint, you need to start swim and bike as you say and I´d suggest:
Swim: do you have a swim background/can you swim? If you can´t swim you´re best trying to find a GOOD TRIATHLON coach who can hopefully help you do the right things rather than learning to swim like a swimmer. You need to try to swim 3 times per week if possible - 30min per time is fine, frequency is important.
Bike: learn how to ride a bike confidenty on the road but you can do a lot of training indoors - you can use a spin bike worst case, but many gyms have Wattbikes as well. Try to bike 2-3 times/week
Run: cut it down to 2 runs per week - you have made gains in running but you need to focus on swim and bike, and the fitness you get from these will help running anyway.
Stop the 4 gym sessions (unless you have enough time to do these ON TOP of the suggested swim, bike and run sessions) - focus on doing what you need to do.
Finally, train at the right intensity - mostly easy - but build specific strength in swim, bike and run sessions (much better that doing gym strength that is non-specific and timeconsuming if you´re time limited); see:

Hope that helps
Start in the pool, get out on the bike short during week, longer on weekend. Throw on the shoes and go for run, sometimes straight after bike. Now you got some routine and rhythm continue, dont get hung up on training plans, do what you can and enjoy the process.
