No. It is Su-27P ("P" means "Interceptor"), rather old modification, can attack only air targets.
It's a copy of the F/A-18
No. First flight of F/A-18 was in 1978, first flight of Su-27 was in 1977.
And yes, you can compare their photos, they are very different.
The F/A-18 was already around when they first flew the SU-27

"The U.S. intelligence community first learned of the new Soviet aircraft from satellite photos in November 1977, about the time of the jet’s first flight. “Simply by looking at the size and the shape of it, it was clear that the Soviets were developing a counterpart to our F-16 and F/A-18,”

In 1969, the Soviet Union learned of the U.S. Air Force's "F-X" program, which resulted in the F-15 Eagle. The Soviet leadership soon realized that the new American fighter would represent a serious technological advantage over existing Soviet fighters. What was needed was a better-balanced fighter with both good agility and sophisticated systems. In response, the Soviet General Staff issued a requirement for a Perspektivnyy Frontovoy Istrebitel (PFI, literally "Prospective Frontline Fighter", roughly "Advanced Frontline Fighter").[3] Specifications were extremely ambitious, calling for long-range, good short-field performance (including the ability to use austere runways), excellent agility, Mach 2+ speed, and heavy armament. The aerodynamic design for the new aircraft was largely carried out by TsAGI in collaboration with the Sukhoi design bureau.[3]

When the specification proved too challenging and costly for a single aircraft in the number needed, the PFI specification was split into two: the LPFI (Lyogkyi PFI, Lightweight PFI) and the TPFI (Tyazholyi PFI, Heavy PFI). The LPFI program resulted in the Mikoyan MiG-29, a relatively short-range tactical fighter, while the TPFI program was assigned to Sukhoi OKB, which eventually produced the Su-27 and its various derivatives.


Soviet Su-27 in-flight
The Sukhoi design, which was altered progressively to reflect Soviet awareness of the F-15's specifications, emerged as the T-10 (Sukhoi's 10th design), which first flew on 20 May 1977. The aircraft had a large wing, clipped, with two separate podded engines and a twin tail. The 'tunnel' between the two engines, as on the F-14 Tomcat, acts both as an additional lifting surface and hides armament from radar.

Actually, Su-27 was developed as a "killer of F-15", not " copy of F/A-18".

Ok. We can say, that F-14 and F-15 were trend-setters for F/A-18, F-16, Su-27 and MiG-29.
