An Esata port is a port you connect a ESata-compatible storage device (HDD/SSD) to.
ESata stands for "External Serial ATA", and as opposed to normal SATA, this port can be found on the outside of the computer so you can easily connect Hard drives to your system. The 2 connectors can't be exchanged.
Short answer: No. They are different and not compatible. Long answer: If the USB 2.0 device happens to be a hard drive that also has an esata port, then you could use the esata port instead.
eSATA-600 at 6.0 Gbps while FireWire runs at 1.2 Gbps.
The companies found which product computers with an esata port are as follows: Hewlett Packard, Toshiba and LG. Esata ports could also be purchased as an external hard drive.

I am building an external hard drive out of an old PC case and I want to have multiple drives in it to maximize storage capacity. But I want it to plug into only one eSATA port. Are there any adapters or things I can use to do this?
eSATA is the fastest of the three.
eSATA refers to a SATA port located externally near other onboard ports. Hard drives, SSDs, and optical drives can be connected to this. It is a SATA port on the outside of the case. This port is commonly found on cable DVR boxes as well in order to add additional storage capacity to the DVR cable box.
