Can you root? If so then why not try Lineage OS. The phones seem old and a lighter OS wouldn't hurt. For battery you can try ACCA (requires root) or Accubatery Also depends on region but 3G gets taken down. WiFi and internet are dependent by tower distance and by how many WiFi clients and networks are around. Try WIFI widget handy tool. Cpu-z to check clock and thermals, ram usage and clocks. I do recommend installing Lineage OS and there are magisk modules if you're willing to try, they might work they might not.

You don't need root to flash.
Rooting is a function within an OS, flashing is the process of replacing the OS.
Root is the equivalent giving Admin permissions in Windows, flashing is equivalent to installing Windows.
Also, rooting requires a factory reset.
No you dont need root to flash, but if you install magisk you need to flash the patched boot image therefore have bootloader unblocked which is needed. What I meant is that if OP decides to root with Magisk it'll just be easier to install Lineages OS(if his phones are supported) than to search for the firmware file to extract boot image since Lineage offers it already extracted
Phone 2: Wi-Fi signal weak or barely functioning, youtube videos buffer and load for much too long on 720p when they shouldn’t need to.

Does that phone have apps which may be eating your resources ? https://f-droid.org/en/packages/eu.faircode.netguard/ With NetGuard you can block access for mobile and / or WiFi per app, or block all including system apps and then allow the ones you need.
Battery/charging:
Verify what's happening (charge voltage/current) using an app like GSAM Battery Monitor or Accubattery. Accubattery can also perform a battery health assessment by monitoring the min/max voltage of the battery after 2 or 3 full charge cycles (it tells you how to do this).
It may be that you have a low power charger, or a cable that limits charge current, a faulty charger, or an app that's eating power.
If it charges slowly, but you have good voltage/current, there may be something running that's consuming battery. Both GSAM and Accubattery will show app battery consumption.
For the network performance issue, resetting is the most definitive approach. Then you'd eliminate software causing issues. Alternatively using a firewall app like NoRoot Firewall, you can bIock network access for most apps and see if performance improves.
But network is a complex question - is it your connection, is it something between you and the servers, etc.
