Yes, it is absolutely no problem. You could even have multiple versions of both 32bit and 64bit Java installed at the same time on the same machine. In fact, i have such a setup myself. You can install multiple Java runtimes under Windows (including Windows 7) as long as each is in their own directory.

Then, should I install 32 or 64 bit Java?

Strictly speaking, on a 32-bit CPU architecture machine, you should install 32-bit java/JRE. On the other hand, on a 64-bit CPU architecture machine, you are free to choose between 32-bit java/JRE and 64-bit java/JRE. Both will work just fine. Mainly because of the memory layout in 64-bit architecture.

Subsequently, question is, what is the latest Java version? The latest version of Java is Java 12 or JDK 12 released on March, 19th 2019 (Follow this article to check Java version on your computer).
