You are mixing up ideas: Free, commercial etc.
The Apache 2 licence is a Free Software licence. Free as in freedom, not as in price. One of the freedoms is to sell copies. Another is to allow commercial use.
What is not allowed in most Free Software licences is to make it become proprietary.
What is meant by Apache 2.0 here when it is being priced?
You can charge a fee (any amount). I don't see anything “here”.
Can I use community edition for proprietary software which will be given to customers?
You can use the community (Apache 2 licenced version), and give copies to your customers. However You must give them the same licence that you have ( unless the licence gives you freedom to do otherwise ). You must not make it proprietary. You must give access to source code for any modifications.
Is the pricing not for software but for support i.e. I can use it freely if not availing support?
The price is not limited. You have the freedom to charge any price (only limited by what your customers will pay). Yes you can use it freely.
You may become liable as the distributor of the software, especially if you sell copies (see local laws). You are free to provide support.
